FIELD: heating.
SUBSTANCE: combustion chamber dynamics reducing system includes combustion system containing many flame tubes and at least one resonator. Each flame tube includes many fuel atomisers installed near effusion plate. Resonator is installed on effusion plate of flame tube. At least one resonator includes the first side containing many openings forming a grid of openings of cold side, the second side containing many openings forming a grid of openings of hot side, and cavity formed with the first side and hot side. Grid of openings of cold side is oriented so that each of many openings in the grid of openings of cold side provides the supply of cooling air jet to the cavity consisting of many openings. Cooling air jet passes through the cavity to bump against the surface facing the second side. Grid of openings of hot side is oriented so that each of many openings in grid of openings of hot side provides the bumping of working fluid medium jet against the surface facing the first side.
EFFECT: reduction of high-frequency acoustic vibrations of the system.
